- This invention relates to improvements in metal pouring devices.

Devices of this character are used to convey molten metal from one portion 'of' a foundry to another, and are also used to pour the metal into molds. The deviceis usually suspended from anoverhead traveling-crane.

When the container has reached a mold, it is usually raised to the proper height for pouring, and aftera portion of the-metal in of the container has been poured, it is necessary to'raise the container again to maintain the nozzle at a given height topermit a further flow of the metal when the container is further tilted. In other words, as the amount of metal inthe container decreases,-the height of the container has'to be raised correspondingly. we will assume thatthe container holds metal sulficient to fillte'n molds, and we will assume that the molds are of the same height, The

container is manually adjusted to the proper height for the first mold. 1 When that has been poured, the amount of metal in the. container having decreased, it is'necessary to raise the container still higher to obtain a flow of metal for pouring the next mold,'andso on untilall are poured. A simple way of stating this'is that the'height of the container mustbeinversely proportional to the amount 7 of metal remaining in the container to maintain the nozzle at apredetermined heightl 'Heretofore, these-various changes in-height have hadto be accomplished by hand, which was necessarily a greatinconvenience It'is one ofthe objects of the pres'enti-nvention to provide a metal pouring device which will automatically adjust the: height-of the i to providecompression springs which willjbe container, and thereby permit the proper fiowoof metal for pouring the molds. T

It is a more specific ob'ect of this invention compressed to varying degrees according" to the amount of metal in the container, to there= by automatically regulate the height of said container and thereby permit proper flow of the metal.

It is a further object of thi s inve ntionto provide adjustable means for varying the normal height of the device. It is a further object of this [invention to provide a frame forsupporting' the container,

which has a rigid guide rod operatingbe- As an illustration,

rollers, which are held in place by pins 2.8,.

tend to eliminate friction and the resulting wear upon the parts.

The upper portion of the U-shaped frame is composed of a slotted angular bar 29 secured to the sides of the frame-bybolts- 31 and nuts 30. The hanger bar 13 is slidably positioned in the slotted portion'of this bar and operates against the roller 32, which is mounted on the pin 33. Pivotally mounted on each end of the pin 33 on each outer side of the frame, is a link member '34. The link members are pivotally connected at their other ends to lever members 35. The lever members are rigidly connected to a tra .sverse shaft 35 which is pivoted to the lower end of the hanger'bar and to the slidable member 25. One of the lever members has connected thereto a handle 36. The lever members arearranged to slide the member along the guide-bar 23 to raise or lower the frame. An adjusting screw 37 limits the movement of the lever arm to prevent it from going past the center line of the frame. The

lower portion of the hanger bar is formed with teeth 38-which are'engaged by the pawl 39, and said pawl is pivoted in the slotted bar --29. The pawl is normally held in engage- 'ment by a spring 40, and may be swung out of engagement by operation of the pawl lewith the teeth, the U-shaped frame is supported upon and prevented from dropping any lower upon the hanger bar.

ver 41. When the pawl is'in engagement i Suspended by the hook-shaped portions 20 is the mechanism 42- for carrying and tilting The operation'of the device is as follows:

WVhen the container is filled with molten metal, there is a downward pressure exerted upon the guide member 14: which compresses the springs 16 and causes a lowering of the 'GIltllG' device.

The device is then brought '-near the molds which are to be filled. By

releasing the pawl 39 and operating the lever handle 36, the contamer is lowered to the proper height for pouring the first mold. The pawl is then released and 1t sprmgs into engagement with the teeth of the hanger bar,

' holding the device at the desired height.

sary to maintain the nozzle of the container at the proper height in order for the metal lower frame,

to continue to fiow. This istakencare of automatically by the compression springs 16. With the decreasing weight upon the springs, the quantity of metal is reduced by pouring, the springs expand nearer to their normal position, andthe container is correspondingly raised. Thus a means is provided for automatically regulating the height of the nozzle of the container to con-v tinue the How of the metal as its quantity is reduced.

From the foregoing description, it will be seen that-the improved metal pouring device is simple in construction and operation, and

is well adapted for the purpose described.
